My editor did exactly what Samantha asked of Michael: asked me why, over and over again. Why I am I telling this story? Why should anyone else care? Why should they read past the first paragraph? Why is this sidebar here?
I always thought editors as being like the New Yorker's Comma Queen, focused on sharpening syntax. But while that is certainly part of their purview, they are masters at crafting compelling stories and tailoring the facts of the matter to the intended audience.
